The answer to your question is -45 and 6 as shown here:
-45 x 6 = -270
-45 + 6 = -39
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 39x - 270 = 0
If so, the solution to factor the quadratic equation above is:
(X - 45 ) (X + 6)
To summarize, since -45 and 6 multiply to -270 and add up -39, you know that the following is true:
x2 - 39x - 270 = (X - 45 ) (X + 6)
